Lu Zhihao World’s Heaviest 4-year-old

Lu Zhihao, who is 3 feet 7 inches (1.1 m) tall and weighs 136 lbs (62 kg), put on weight dramatically since his appetite grew when he was 3 months old. His worried parents took him to several hospitals, but the reason for his obesity remains unknown, though it is possibly due to his dietary habit, according to local media.
